USB: UAS: introduce a quirk to set no_write_same
commit 8010622c86ca5bb44bc98492f5968726fc7c7a21 upstream.
UAS does not share the pessimistic assumption storage is making that
devices cannot deal with WRITE_SAME. A few devices supported by UAS,
are reported to not deal well with WRITE_SAME. Those need a quirk.
Add it to the device that needs it.
